CHRIST MAUL, 0F CHICAGO, ILLINOIS, ASSIGNOR TOA A. MAGNUS SONS COMPANY, OF CHICAGO, ILLINOIS, ACORPORATION OF ILLINOIS.

HYDROPNEUMATIC GAGING- APPARATUS.

To all 'whom t may concern:

Be it known that I, CHRIST MAUL, a citizen of the United States, residing in Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Hydropneumatic Gaging Apparatus, of which the following is a specification.

This invention .relates to measuring devices for barrels, kegs, and other containers.

The invention consists substantially in the combination and arrangement hereinafter described and illustrated in the accompanying drawings, and more particularly set forth in the appended claims.

In the drawings: Figure 1 is a side elevation of the complete -device and the barrel to which the device is applied being shown in section. Fig. 2 is a front elevation of the measuring tank or reservoir showing the gage glass and scale. Fig. 3 is a sectional view of the bunging device. Fig. 4 is a sectional view of the observing lantern and check valve.

In this invention, a tank 1 mounted on a suitable base 2 is provided for holding the liquid, preferably water, used in measuring the capacity of a vessel such as that shown at 3. The tank l has a connection 4 provided with a valve 5 communicating with any source of liquid supply for initially fillingthe tank. After the tank is once filled, the valve 5 is kept closed,I and the water in the tank used over and over again for measuring vessels. Communicating with the top and bottom of the tank 1 respectively are pipes 6 and 7 connected with the gage glass 8. The gageglass 8 has freecommunica'tion with the atmosphere at its upper end through an opening in the fitting 9, and is provided with a vent--cock 10 at the lower end thereof.

Fastened' to the tank behind the gage glass is an angular scale 11, one surface of which is graduated so as to measure in gallons the amount of liquid allowed to flow from the tank at any one time.- The other surface of the scale is provided with half gallon graduations. Connected to the bottom of'the tank, and communicating with the interior thereof is a pipe 12 adapted to be closed by Specification of Letters Patent.

a valve 13. Connected to the end of the pipe 12 is `a flexible tube 14, preferably a rubber hose. The tube 14 is connected to the upper end of the pipe 16, and a valve 15 is provided for opening and closing the upper end of the pipe 16. The pipe 16 is adapted to be inserted into a barrel or keg through the bung-hole thereof, and a bunging device 17, to be later described, is provided for sealing the opening about the pipe 16. A stand 22 attached to the base 2 is provided for holding the barrel A3 in place while it is being measured. A pipe 18 communicates with the interior of the barrel 3 through the bunging device 17, and is provided with a check valve and observing lantern 19 to be later described, and also with a three-way valve 20 arranged to connect the pipe 18 alternately with the atmosphere and with a source of pneumatic pressure through the pipe 21.

The bunging device 17 includes a member 23 fitted about the pipe 16, and having an opening' 24, which communicates with the interior of the barrel being measured, and also with the interior of the pipe 18 as shown in Fig. 3. Upon the lower end of the member 23 is an integral ring or abutment 25 having upwardly beveled edges adapted to hold a gasket 26, preferably made of rubber or similar material. Resting on the upper rounds the pipe 16. When the bunging de-V vice is inserted in thebarrel or keg, the member 29 is turned so as to press downwardly on the shoulder 28, and at the same time pull upwardly upon the member 23, thus-` compressing the rubber gasket 26 and causing it to expand laterally and make an air tightconnection between the bunging device and the barrel. The only communication to the barrel is then through the pipe 16'y or the pipe 18.

Connected with the pipe 18,' by means of top of the barrel.

serted through the bung-hole and the bung- The upper end of. the observing lantern is provided with a fitting 32, and the fittings 31"'and32 are connected by means of -bolts` 33. A cylinder or -tube 34, preferably of glass, extends between the fittings 31 and` 32, and is provided with packing rings 35. so as to make an air tight connectionjbetween the fittings and the glass. The upper endv of the fitting 31 is Iprovided with a screen 36, and the lower end of the tting 32 is provided with a beveled valve-seat 37. .On the interior of the glass cylinder 34 is provided a ball-valve 38.

The operation -of the device is as follows: The valves -5 and 15 being closed and the tank 1 filled with water until the waterin the gage 8 registers with thegzero reading on the scale 11, the barrel or keg 3 is placed on the stand 22 with the bung-hole at the The pipe 16 is now inphere. The valve 15 is now opened, and water runs from the tank l through the pipes 14 and 16 into' the barrelfforcing the air out of the barrel through the pipe 18 and valve 20. The air passes freely through the observing lantern 19,- since the ball-valve 38l restsupon the screen 36 leaving a free passage through the lantern. When the water v 'hasvfilled the barrel', vand begins to rise in the pipe 18, 'it lifts the ball-valve 38-into contact with the valve-seat 37, and closes the passage. so that no more Water can fiow into the barrel.` When the valverises in the lantern, the operator knows that the barrel is full. It will be noted that in addi-tionto the Water required to fill the barrel, a certain amount of water has been used to fill the pipe 18, and the portion of the pipe 16 A displaced bythe` portion of the pipe 16 on the inside of the barrel. The amount of 'water that has been drawn from the tank 1 f is therefore equal to the amount required als to lill the barrel, and this amount is ascertained by the readings on the scale 11 opposite the top of the water in the gage valve 8.

After the reading has been taken the valve the water out of the pipe 18 back into the barrel through the 'opening 24. As Vthe air enters the barrel through the opening 24, it-

brought as near as possible to the bottom of the barrel, practically all of the water will be forced out of thebarrel into the tank 1. The valve 15 may now be closed,

the bunging device 17 released, the pipe 1 6 removed from the barrel, and the barrel replaced -by another to be measured.
